put finger to keyboard and composed:
I have an old GPS1810OH Power supply and I wanted to know if any of you
might have one on your bench... Mine has a semiconductor that has the
top of it fried and I can't read the part number... If anyone has one
that could read off the part number, or better yet... a drawing of the
regulator board... well... know that is too much to ask.
Where is the heatsink for the pass transistor (?) for the uA723C
regulator?
Where is the missing relay (top), and if it isn't missing, then why is
the PCB populated with its support components?
Can you trace the circuit around IC3?
What is IC2?
- Franc Zabkar
Ic2 seems to be a 741 op amp... I thought that IC3 MIGHT be the same..
and it PROBABLY is.. Just not sure... Havn't taken the board out yet
and tried to retrace what is going on.. was just at the research stage
where I am trying to find out if there are any drawings or someone that
has had one of them open before.
Thanks!!
